It's a good idea to know about the objectives, but only a few maps will have them, even fewer will you ever see the objectives taken, and even of those it's going to be pretty rare. But you should still know about them and they can be found in the key.

Now "defeat objectives" as you call them, the things that you will instantly lose for are also not very common on maps, but you should DEFINITELY pay attention to them because people will use them to get you out.
